can you grow plants indoor using a regular lightbulb?

Answer 1

Keep it close to the plant other wise the plant will have to strain to get enough light.
They make special light bulbs that simulate real sunlight for less than $5. Remember to pay cash so they wont track your purchase.

Answer 2

Yes, with qualifications.
The main difference comes in the spectra of light emitted by the incandescent, flourescent and specialty plant lights.

Incandescent lamps are totally ineffective as grow lights; they have very limited spectrum since they are intended to read by. They are very inefficient in their use of electrical power to light output so cost to much. They also put off far too much heat per watt to use in horticulture. Once the light is close they burn the plant and if at a safe distance there is insufficient light.

You can use standard fluorescent tubes for starting seedlings indoors, but to grow your plants farther they won’t get the wider spectrum of light they require. That is when you need tubes that are designed to promote plant growth.

Vegetables or foliage plants grow best in blue spectrum light, which is a cooler form of light. Metal Halide lights are the most popular form of blue spectrum lighting.
Flowering plants grow best in red-orange grow light. The best type of red-orange light is the high pressure sodium light (HPS).
Other bulbs HID, Mercury Vapor, and LED bulbs

Answer 3

You can, but you get bigger buds with proper lighting.
